OpenStack Compute (nova)

cURL request hypervisor information

Asked by Fawad Khaliq

Hi,

I am making some HTTP requests using cURL to the OpenStack API to gather information about my OpenStack deployment.
I have used "http://api.openstack.org/" for the URI information about different sets of requests. However, I need information about the hypervisor: its IP addresses etc. I have not been able to find a way to access hypervisor information from the OpenStack cloud I have deployed.

To try different things, I looked at the URIs used in the python nova-client documentation and it recently added the OpenStack hypervisor information option and it uses the URI like "/os-hypervisors/detail/" but this does not work for me. It simply gives me an HTTP 404 error.

Can somebody please help me find a way to get the hypervisor information (IP addresses at least) using cURL requests?

NOTE: I am using the OpenStack Diablo Release. I have all the services running except for nova-volume and Swift.

P.S. If you need more information, please let me know. I will be happy to provide you with that. I really need to get this working.

Thanks a lot.

Um...if you are using Diablo you won't be able to access the latest os-hypervisor extensions:

https://github.com/openstack/nova/blob/master/nova/api/openstack/compute/contrib/hypervisors.py

as they have been added in Folsom.

Fundamentally, I am not sure why you would need to know such low-level info, like hypervisor IP addresses; what are you trying to achieve?

Thank you for your response Armando.

I also have Essex setup now and it gives me the same 404 error, means the information is not available.

I need this information for a small university project work I am doing.

Are you sure it will be in the Folsom release as it will be coming out in Fall 2012? Why not in Essex?

Thanks,
Fawad

Essex is closed: http://wiki.openstack.org/StableBranch

If you need new functionality you can try and propose it for trunk:

Hope this help,
